Answer:
It’s b even check quizzes
Explanation:
0.750l = 750ml
14% of 750ml is 105
therefore, the 750ml bottle of wine has 105ml of alcohol
Ba(NO₃)₂ + Na₂SO₄ → 2NaNO₃ + BaSO₄
The reaction goes to completion because it has the same amount of elements in the reactants and products.
Answer:
-1.05 V
Explanation:
A detailed diagram of the setup as required in the question is shown in the image attached to this answer. The electrolytes chosen are SnCl2 for the anode half cell and MnCl2 for the cathode half cell. Tin rod and manganese rod are used as the anode and cathode materials respectively. Electrons flow from anode to cathode as indicated. The battery connected to the set up drives this non spontaneous electrolytic process.
Oxidation half equation;
Sn(s) ------> Sn^2+(aq) + 2e
Reduction half equation:
Mn^2+(aq) + 2e ----> Mn(s)
Cell voltage= E°cathode - E°anode
E°cathode= -1.19V
E°anode= -0.14 V
Cell voltage= -1.19 V - (-0.14V)
Cell voltage= -1.05 V
